Application filed March 2, 1916.. Serial No. 81,725.

T0 all whom t may concern Be it known that I, FORD MGEN'HRE, a citizenof the United States, residing at Shelby, in the county of Cleveland andState of North Carolina, have invented certain new and usefulImprovements in Churns; and I do declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilledin the art to which it appertains to make and use thesame.

This invention relates to improvements in churns, and the principalobject is to provide an article of this character, the parts of whichcan be readily dismounted for storage or the like.

Another object is to provide a churn having an improved means forshortening and lengthening the operating rod which supports the dasherso that said dasher may be moved toward or away from the bottom of thecream can.

With these and many other objects in view, my invention resides incertain novel features of construction, combination and arrangement ofparts which will hereinafter be more particularly described and claimedand shownin the drawings wherein Figure 1 is a central verticallongitudinal section of the upper portion of the cream can and theoperating means for the dasher;

Fig. 2 is a transverse horizontal section taken on a plane immediatelyabove the dasher D Fig. 3 is a similar view taken on the line 3 3 ofFig. 1, the parts however being on an enlarged scale; and

Fig. 4 is a detail vertical section taken on the line le-4 of Fig. 3.

As shown in the accompanying drawings, my improved churn comprises asupporting base 1 preferably rectangular in plan view and raised abovethe floor by the feet 2, said base having a rectangular recess '3 in itstop for the reception of a similarly shaped cream can or receptacle 4-in which a dasher D is designed to rotate. A pair of supportingstandards 5 are secured by their feet 6 to this base l adjacent theopposite edges thereof. Each of these supporting standards issubstantially inverted V-shape, the legs 7 thereof converging from theirfeet 6 to the upper end where they merge into a shank 8, theintermediate port-ions of the legs being strengthened by the transversebar 9 formed integrally therewith as shown in Fig. 2.

The shanks 8 are provided with a plurality of vertically alined spacedapart sockets 10 which receive the vertically alined spaced apart lugs1l carried by the opposite ends of a frame 12. Flach series of lugs 11has a vertical aperture 13 which alines with an aperture in each shank 8in order that a connecting pin or bolt 14 may be placed therethrough asshown in Fig. 1 to secure the parts in operative position. From anexamination of the drawings, particularly Figs. l and 2, it will be seenthat the receptacle 4 is disposed between the supporting standards 5 andits upper end is spaced a considerable distance below the frame 12.

This frame l2 is designed to support the means for rotating the dasherD, and as shown is substantially rectangular in cross section, its topbeing flat while its under side is arched as at 15. The central partdirectly over the center of the receptacle L is provided with anaperture 16 in which a sleeve 17 is disposed. the upper end of saidsleeve'having a beveled gear 18 lixed thereto. This gear 18 vpreferablyhas acollar formed integrally therewith through which a set screw 20extends for attaching the sleeve 17 and the gear together. rThis beveledgear 18 is designed to mesh with a larger beveled gear 21 carried by oneend of a rotary shaft 22 which is mounted in bearings 23 supported by abracket 24 integrally formed with said frame 12. The shaft 22 and gearare rotated by means of a crank 25 iixcd to the opposite end of saidshaft, said crank having ball or other weight 26 on one end to aid inoperating the same.

For mechanically operating the beveled gears 18 and 21, I provide a flywheel 27 fixed on a rotatable shaft 28, said iiy wheel being adapted tolreceive a belt or any other driving connection from a suitable sourceof power (not shown). This shaft 28 is mounted in the vertical plane ofthe shaft 22, but in a horizontal plane below that occupied by theothershaft, and is supported by the bearings 29 formed on the u per sideof said frame 12. A pinion30 is xed to the end of the'shaftl 28oppositeto the fly wheel and meshes with the internal gear 31 which isintegrally cast with the beveled gear 21 as shown in Fig. 1. Thisarrangement permits the beveled gear 18 and the sleeve 17 to be eitheroperated manually by the crank 25 or mechanically through powertransmitted to the shaft 28'. It will also be seen that by providing`theV fly wheel 27, the manual operation of the device will be greatlyfacilitated, because ofy the fact that this wheel will act as a balancewheel', its momentum causing the` gears to move with greater ease onceit has been started.

Furthermore by providing means for connecting the gear 18 on the upperend of the sleeve 17, said sleeve which has a head 17 on its lower end,will be held in said frame 12, and the gear will be maintained incooperative engagement with the larger gear 21. This head 17 has athreaded opening for the reception of a set screw 32 for locking anoperating rod 33 therein so that it may be rotated with the gear 18.This operatingy rod extends downwardly through an opening 34 in thetwo-part cover 35 of the receptacle 4 and' into the interior thereof.

As shown the lower end of the rod 33 below the head 17 islprovided withgrooves 36 which are disposed at diametrically opposite points thereinand extend longitudinally thereof. This end is designed to-slidablyreceive the stem 37 of the dasher D, said stem being provided with alongitudinally extending bore 38 for this purpose. Before inserting therod into the bore, a cylinder 39 is placed therein, the inner diameterthereof' being substantially the same 4 as the rod 33 to prevent itswabbling. The

lower end of the cylinder 39 has a pin extending therethrough, said pinalso extending through the stem 37 to prevent one shifting in the other,the other end of. the cylinder being provided with an annular liange 40which has a depending portion 41 to form a cap which slips over the freeend'I of the stemV 37 as shown in Fig. 1. As shown also in this figurethe cap is disposed in theV opening formed in the top of the twopartcover 35 of the receptacle, thus forming av bearing surface for thepreferably wooden stem of' thcdasher. Although it is sometimes necessaryto regulate the position of the dasher within the receptacle, thisseldom takes place except when receptacles of different heights areused. In other words if a shorter receptacle was disposed on the baseofthe device, the dasher would be lowered until the cap on the endl withthe stem was i disposed within1 the opening in the top 35 in the mannershown in Fig. 1.

As shown, fastening elements 42 pass through said flangeinto the stem.This cap member has an opening through which the rod 33 extends into thecylinder 39, and

surrounding this opening is a sleeve 43, itsV inner diameter beingsubstantially the same as the diameterof the rod 33. The sleeve 43is'provided with a pair of inwardly extending lugs 44 which are disposedin the grooves 36 to prevent the rotation of the stem 37 thereon, whileat the same time allowing said stem to be moved vertically. The sleeve43 is also provided with a set screw 45 by which the stem may be'securedin its adjusted position on the rod.

The lower end of the stem 37 has a head integrally formed therewith,`said head being square in cross section and taperedY from its uppertoward its lower end. Dasher wings 46 are secured by their sides to theflat faces of the head four of these wings being provided, one. for eachof the faces.

Gnly one end of each wing extends beyond the edges of each face,

From the foregoing descriptiomit will Vbe seen that the several partsofthe device may pose of storage or the like, the supporting standardsbeing readily removed fromthe base 1, and the frame 12 disconnected fromthe ends of the standards. Whenthe bolts 14 have been removed the frame12 can be readily removed from the ends of the standard, a hand grip 47being provided so that the same can be readily lifted from place. Thismember 47 is arched and its lower ends are formed integrally with thebearings which are supported by the bracket 24.

While I have described the elements Vof my invention with Vconsiderableminuteness ofdetail, it is obvious that various changes may be made inthe form and proportion thereof without departing from the principle orspirit of the invention as defined in the other end beingA beveled anddisposed flush with the edge.
